Zimmer Persona® Knee

Zimmer Persona
Knee - The Personalized Knee System

Zimmer is redefining knee arthroplasty and ushering in a new era of
personalization with the introduction of the Persona Knee.
The Persona System makes the most clinically successful knee
replacement more personalized than ever by focusing on the unique
needs of the patient, surgeon and institution.1

We used our leadership and knowledge of the natural movement of the
knee to develop the Persona Knee. Working with more than 50
of the world’s most respected orthopaedic surgeons, and utilizing
analytics from both genders and 1,500 different bone types from 26
different ethnicities, Zimmer was able to create the most anatomically
accurate knee implant.

The result is the Persona Knee. Our goal was to come as
close as possible to the remarkable mechanics of the human body…where
form truly does follow function. Welcome to the Persona Knee
– putting the person back in knee replacement.

Knee replacement implants have improved the lives of millions, and
today knee replacement is one of the most successful medical device
surgeries. More surgeons trust Zimmer NexGen Knee
Replacements for their patients than any other total knee replacement
surgery system. As the leading orthopaedic implant manufacturer, we
have one overriding commitment: To restore mobility, alleviate pain
and improve the quality of life for patients around the world.

Overcoming Limitations. Minimizing Compromises.

Until the Persona Knee, limitations in knee arthroplasty
systems required surgeons to accept compromises, which have created
surgical inefficiencies and posed challenges to realizing desired
patient outcomes. The Persona Knee equips the surgeon with a
comprehensive system that provides remarkable intraoperative flexibility.

The result is an implant system that addresses the unique needs of
the patient and accommodates surgeon-specific preferences — all while
empowering surgeons to minimize “trade-offs” and better optimize results.

Persona Knee features include:

Innovative morphologic knee implant designs

Comprehensive sizing with tighter increments

Side-specific kinematics

Differential conformity
articulation

Cruciate Retaining and Posterior Stabilized
philosophies

Integrated intelligent instruments

The Persona Knee incorporates an implant design that
accommodates up to 155° for PS/CR or 145° for UC, of safe high flexion
as required in daily activities. It has improved backside wear
performance due to unrivaled locking mechanism and surface finish on
tibia components that virtually eliminate micromotion. Also, up to
155° of high flexion provided by femur design maintains optimal
contact area through flexion in daily activities.

Longevity

Several features of the Persona Knee contribute to
longevity. The “active stabilization” Vitamin E-enriched polyethylene
is formulated to maintain initial mechanical strength and oxidation
resistance for the long term.2
